Almost anyone can drive a car, but not everyone gets paid for it. Drivers are responsible for everything from driving customers from point A to point B, to delivering packages to clients, you have a range of what exactly you want to be driving. If you're going to be delivering packages, you'll want to build up your upper body strength in case you have to lift heavy objects.
As far as driving people around, you might want to brush up on your communication skills, either that or blast your music during the ride. Some drivers are especially helpful to tourists who are curious about the area. In these instances, your favorite restaurant or activity might come in useful.
The hours you'll work as a driver can range dramatically. Your work schedule will depend on who you're working for and if you're able to set your own hours. There are some companies where you'll work 60 hours in 7 days, but other companies will only require 40 hours. If there's anything to take away from being a driver, it's that the job is nothing less than interesting.
